, Ref.erring nowgmore particularly to the draw-,

ing;:it willappear that the register is adapted for installation in awall 8 havingan opening 9 there-1 through into which the end portion ofa pipe-or stack 10 extends. Adjacent the outer face of the wall; theopening is enlarged; as; at 11, to receille innerportions of y, theregister,

as will later beiexe,

- Inorder to fit withinthe, enlargement 1 1 Wall opening, andto engagethe, end portion ofthe stack, .-the register isprovided with arectangular frame; ,The sides12 andends 13 of said frame are all anglebars. Said frame is disposed adjacent the innersurface of a registergrille 14 in a mannerso that one set of legs of the angle bars edge wiseengage theinner surface of the grille Hat "ight angles to it the planethereof and slightly in wardly; of the periphery of the grille, whilethe other set ofi-legs of the angle bars lies in aplane rearwardly ofand parallel to said inner surface of the grille. Each of thelast-mentioned legsof thexangle bar-sides and ends 12 and 13 of theframe carries, against the face adjacent the grille, P in; of: o u i aly eedin Li a? m t lic strips or bars 15 and -16,,which;bars are tightlysecured to the angle bars by screws 17 The outer; side edges of saidbars 15 and lfi terminate-in: wardly of, theinner face of ,theother legsof the anglebarsof the frameto provide continuous e aaesa r s es Also, hs th a eltfi e spaced rearwardlyof the inner face of the" ille 14 so asto acconnnodate the he d 91%? 17 which donut pass into the grille: '1

;;;As was previouslymentioned the end portion of pipe or stack 19extends into the wall opening l9 is surrounded by theangle bar framewith en h ta =v en n e m e a-,,collar. The extreme end 1 portion of the.stack ilfieh d laterally l letri a leswes at 1,9 and said flanged lportion 49 1s connected are ame w e a m b w nt ve -i 99s ar a l6rs i s on in F s. ,2 n I li o s r iqny f 11119 9 1 15 .1 t p l b thee of m or cthe t me o properljoints and: connections; 'Ifhe arrangement is bestdisclosed in the broken, away portions of Figs. 1 and Land it willappear that insofaras the i an b r 2 e ecm a he, l s thereof ;which areparallel with the plane of the 'grillehave their end portions cut awayas at 29,

toreceive the ends oi the end angle bars 13. Said endsof the angle bars13are overlapped byend portionsof theflathars 16 of theframe ends,whichiatter end portionsabut against the ends of the bars 16 of theframeksides, the latter bars terminating short of the angle barscarrying the same. This also true of all of the flat bars 15.

, Also, as,f,or thewflangej19 ofthe stack, square pieces are out out'ofall of the corners thereof.

" The grille 14 is a rectangularinetallic sheet,

and, save for a substantial margin, is of lattice- -work or otherornamental open-work design to permit the flow of air therethrough.Welded or otherwise secured to the innerv face of the marginal portionof the grille, substantially inwardly ,of the edge portion thereof, is"asealing frame formed of angle members. The legs 21 of said, members aresecured flatly against theirmer surproject rearwardly, slightlyoutwardly therefrom frame extend into and lodge in the recesses 18.

Due to the slight outward angle'to said legs 22 andto thefact that thesame are yieldable, they impinge in the recesses between the outer edgesofthe flat bars 15 and 16 and the inner faces of the angle bars 12. Aswill be seen from Figs. 2

short thereof.

and 3,-an absolute seal is effected between the end portion of-the'stack and the component parts of the register whereby there-canbe'no leakage. The grille is held in this position by screws 23 whichextend through marginal portions of the grille, the legs21 of thesealing frameand into tapped openings provided therefor in thesuperimposed portions of the bars 15 and 1-6 and the angle bars 12. V

A modified form of air duct register isillustrated in Fig. 5 wherein theinner rectangular frame is composed of channel bars having inner and'outenlegs 24'and 25 respectively at right angles-to the plane of thegrille 14, and rear legs'26parallel withthe plane of the grille andspaced therefrom. The 'legs'25 engage the rear face -'of the grille,while the legs 24 terminate The end portion of the pipe or stack 10 isprovided with anannular outwardly, rearwardly turned hooking flange '19which hooks over the'short inner legs 24 of the channel bar frameandabuts against flat bars 27 secured within the channel members. Thesealing frame earried by the inner-surface of the'marginal portion ofthe grillecomprises angle strips secured to the grille in a rectangularformation with legs 2'1"th'ereof-against the grille and with their etherlegs 22' extending'rearwardly inwardly from the inner-edges ofjthe legs21, said legs 22' being springy oryieldable. The hookedend of the pipeengages the channel frame as'shown, and said channel frame lodges within'the enlargementll of the wall opening. The grille 14 fits against theface-of the wall overthe opening, as in the principal form of theinvention, and the legs 22' of 1 the sealing frame extend into thechannel membersand impinge against the hooked end of the stack to forceit against the channel legs 24," thereby effecting a; seal- The grilleisremovably held-inposition by means of screws 23 extending through thegrille, the sealing frame legs 21, and into tappedopenings in the bars27 and the channel members.

The improved air duct register construction is one which has greatutilityv in,he ating,.ventilating, and air conditioning systeminstallations. By virtue of the construction disclosed a gas tight jointis eifected between the stack end and the register and the joint orconnection is easily 'ried thereby within the recess therefor in theinner, connecting frame. The yieldability of the projecting legs of thesealing frame is of importance because said legs yieldably impingeagainst the inturned portion of the stack and insure a seal. The grilleand other parts, may be easily removed for repairs or replacements.

From the foregoing description it will be seen that the improved airduct register is both simple and novel, and is well adapted for thepurposes described' What we claim as our invention is: 1,1. Incombination, a register including an inner, angle bar frame with anopening therethrough and having a rectangular flange extendingsubstantially parallel to the sides of the open ing through the frameand having another 'flange substantially at right angles to the firstflange, a. pipe extending into said frame and having a bent end portionoverlapping the latter flange of the frame, .barsfor clamping said pipeend portion to said frame flange, and a grille detachably connected tosaid frame and having a rectangular yieldable flange extending withinsaid frame adjacent the outer edgesof saidbars and impinging against thefirst-mentioned frame flange for sealing and-grille locating purposes.

2. In combination, 'a register including an inner channeled frame, oneset of side legs of 'the channeled members being shorter .than' theother set of side legs of' said channeled members, a pipe extending intosaid frame and having a hooking flange extending over the short legs ofsaid channeled members of the frame, and a grille detachably connectedto said frame and having a yielding flange extending into the channel ofsaid frame and engaging the hooked pore tion of the pipeand portions ofthe channeled I frame for sealing and securing purposes.

/ 3. In combination, ai register including an inner frame, the frameelements being of angular'form in cross-section and each including apair of legs, a pipe extending into said frame and having a hookingflange extending'over one setof legs of, the frame, and agrilledetachably connected to the frame and having a yielding flange extendinginto the angled frame and engaging the hooked portion of the pipe andportions of the frame for sealing and securing purposes.

4. An air duct register, comprising an inner frame having a. flangeextending substantially parallel to the sides of the opening through theframe and having another flange substantially at right angles to thefirst flange, a bar carried by one of the flanges of the frame, a pipehaving a bent end portion extending within said frame against the bar,and a grille detachably connected to said frame and having a yieldableflange extending within said frame adjacent the engaged end of the pipeand against said bar for sealing purposes. r
